FLOOR STRUCTURE HAVING ELASTIC FUNCTION AND METHOD OF CHANGING HARDNESS OF ELASTIC FUNCTION

PROBLEM TO BE SOLVED: To provide a floor structure having an elastic function which hardly forms local unevenness or gaps, and a method of changing the hardness of the elastic function. SOLUTION: The floor structure includes: a plurality of plate members 10 forming a floor board 2 by being connected in the planar direction; a plurality of supporting members 20 arranged on a lower face 12 of each of the plate members 10 at predetermined intervals to support the plate members 10; a pair of connecting parts 30, 31 respectively arranged on an upper surface 11 and a lower surface 12 of an edge 13 of one plate member 10 of the mutually adjacent plate members 10, 10; a fixing member 40 fixing one plate member 10 of the mutually adjacent plate members 10, 10 to the other plate member 10; and a restricting member 50 detachably arranged on an outer peripheral edge 2a of the floor board 2, formed by connecting the plate members 10 in the planar direction, to restrict parallel movement of a Tatami 3 laid on the floor board 2.
